, LOOSE-LEAF BINDER.

Application filed June 25, 1927. Serial 1W0. 201,444.

provide a device of the type described, which the rings are so fashioned as to grip more firmly when stress is applied to the ho whereby the rings are prevented from be-. coming accidentally opened.

Other objects and advantages willappear in the following specification, and the novel features of my invention will be particularly pointed out in the appended clanns.

My invention is illustrated in the accompanying drawings forming a part of this application, inwhich Figure 1 is a perspectiveview of the de-' vice; Y a Figure 2 is aside elevation of one of the rings showing it imbedded in the support;

Figure 3 is a view taken along the line 3-3 ofFigure2; Y Figure 4 is a top plan view of another modified form of the device; Figure 5 is a sectionalong the Figure 4;

Figure '6 1s a view along the line 6-6 of- Figure 5;

Figure 7 is a section along the line 7 ,7 of Figure 8 illustrating another modified form oi the device and Figure 8 is a section along the line 8-8 of Figure 7 In carrying out my invention I provlde a support 1, see Figure 1, which is preferably made of wood, because of the 'cheapness of the material. The form of'the device shown in Figures 1, 2 and 3 is the form that is-the least expensive to'manufacture of the various Q forms shown in the drawings, A plurality of wires 2 are fashioned into circles or rings and have theirends inserted in openings 3 in the support 1. Figure 1 clearly shows how the short portion of the wi re 2 projecting from the opening 3 is bent back upon itself and imbedded in the recess i for providing an eyelet 5, and for preventing rocking and low line 5--5 of gitudinal movement of the ring in the opening 3. The opposite end of the ring 2 is hook-shapedat 6- and is removably receivringlcauses the hook 6 to bear against the side of t e eyelet and any stress or strain placed upon the leaves 7, will cause the hook 6 to able in the eyelet 5. The resiliency of the I more firmly contact with the eyelet and thereby prevent the accidental opening of the ring.

As many rings as desired may be provided in the device and it will be noted that these rings open independently of each other, so that in case one-ring or more accidentally opens, the other rings will retain the leaves and prevent them frombecoming mixed up.

In standard loose leaf binders the rings are connected to a common opening device and if one ring opens all will open. The closing means on standard devices cannot withstand the stress of a large number of leaves pulling against the rings "at-the same time. In the present device the hooks 6 will more firmly engage with the eyelets when pressure is-applied.

, Figures 4, 5 and 6 show-anotl1er modified form of the device in which the supporting back 13 has openings 14 therein for receiv- :ing a U-shaped portion 15, see Figure 5, of

a ring 16. Part of thewire forming the ring 16 is shaped into an eyelet 17 and the end of the wire is received in an opening 18 in the support '13: The operation of'this form of the'device is identical to the operation of the form shown in Figures 1, 2 and 3 and therefore needs no further description.

Still another manner of. securing rings to thesupport is shown in Figures7 and 8. In

this form of the device the ring 19 is first formed with a book 20, an eyelet 21. and a zigzag portion 22. The rings are then placed ina mold, not shown, and metal is flowed into the moldfor forming a supporting back 23. The metal will cover the zigzag portion 22 and will also cover the end 24 of the eyelet 21. In this way the rings 19 are securely imbedded in the support 23 and the zigzag portion 22' not only prevents the ring from rocking in the bore 25, but also from longitudinal movement in'the bore; It is obvious that the rings 19 may be riveted or soldered to, the

supporting back 23, if desired, and. then the hook 20 may be received in an opening in the back, 23. v

Although I have shown and described.

various embodiments of my invention, it is 2. In a loose leaf binder, a support, split to be understood that the same is susceptible rings carried by said support, one end of each of various changes and I reserve the right to ring being fashioned into an eyelet, the end employ such changes as may come Within the of the eyelet being embedded in said support, a scope of the appended claims. whereby said support forms a part of the 15 I claim: eyelet, the other end of each ring bein re- 1. In a. loose leaf binder a plurality of movably receivable in the eyelet assoclated rings having a zigzag portion and a back for therewith. said rings formed by flowing metal ,over the V 10 zigzag portions for enclosing these portions.
